Final answer:
Biotechnology is primarily used in the medicine and agriculture industries, where it enables the creation of medical treatments and enhances crop yields and quality. It also has applications in food science.
Step-by-step explanation:
Biotechnology is most prevalent in the medicine and agriculture industries. In medicine, biotechnology plays a crucial role in developing treatments such as vaccines and antibiotics and enables the production of proteins for therapies through genetic engineering.
The field is also integral to agriculture, where it is used to enhance crop yields and quality by increasing resistance to disease, pests, and environmental stress.
Furthermore, biotechnology has significant applications in food science, including the development of transgenic crops and the use of fermentation techniques.
